Thanks Brad!
Tunnel project:
@ 1:34 Broken precast road segments can be seen in the stacks.
@ 1:39 More broken segments. As observed by Dessie yesterday... Notice the lack of rebar. Indicating they probably used fiber reinforced concrete. What I don't understand is why they didn't test a new design prior to installing over a hundred of these segments in the tunnel? Certainly when the segments began to fail prior to installation or during installation, as seen in Joe's video 7/29/24 at the 19: 56 and 20: 02 timestamps.... It would make sense to stop all work and send some of the segments to a materials testing lab to see how much load they actually can carry. It appears they didn't do that.
@ 1:42 More broken segments.
@ 2:34 A good close up view inside the tunnel.
Westside storage yard:
@ 6:07 The number of transformers has grown to 52. These transformers appear similar to the ones used for the Megapacks.
2:04 Is that cut up orange fiber optic cable?
@@bigtvjunky9119 Cut up orange fiber optic duct. Which is what the fiber optic cable is pulled through. Two spools of it can be seen @ 1:47 (Bottom).
@@DavidJohnson-tv2nn Could they have been trying to pull the fiber and run into a kink in the duct?
@@bigtvjunky9119 Hard to say for sure since we can't see into the tunnel. The fiber duct could have also been damaged during removal of the road segments, or even worse... If someone tried to drive through the tunnel and there was a punch through when a road segment failed. Of course, this is all speculation.
Thanks Brad

1:35. Westside, Tunnel Project. Removed invert slabs (road decks). Broken decks don’t appear to have rebar or rebar mesh. Likely to have been fibre reinforced concrete, and evidently unsuitable for use in this application. A test gone wrong.
2:08. Westside, Tunnel Project. Slabs are being removed and initially held here while the grout/filler is busted away for the short edges (tunnel liner interface), and the fixing brackets removed and tossed in a bin for re-use or recycling.
3:37. EOL, Transport Yard. Cybertrucks with frunks open. Some glitch being fixed.
6:09. Westside, storage. 52 transformers today. Logo the same as that on the BESS installation transformers. Magnetron of Columbia.
8:07. EOL, Transport Yard, south. Rebar cages for the lighting tower footings. Sparkies pulling cables through the ducts/conduits.
8:35. Southend, west. Apron. Right. Black vaults. Grease trap. Permit on the Travis County site and on the Austin City site for grease traps for the CyberCafe. 8000 gallons 30,000litres from memory.
Left. Excavation and trench shield likely for the grease trap.
8:41. Southend, west. Apron. Bottom right. 3 invert slabs from the tunnel.
9:25. Southend, south. West Fire Escape Passage. Assembling the staging for the roof formwork.
9:49. Southend, south. Central Fire Escape Passage. Scaffolding. For the application of a waterproof membrane perhaps.
10:56. Southend, east. Level 1. Right of centre. 2 rows of narrow formwork.
11:22. Southend, Cooling Tower. 3 sizes of pipe on the saddles under the tower. The brown pipe the largest.
14:01. Stamping, Apron. Industrial gas delivery.
6:09 Maybe your initial speculation about a new Megapack installation is correct. 52 transformers would mean 104 Megapacks! But my point remains that it wouldn't buy them a whole of backup time. Thirty minutes to a few hours depending on the final number of Megapacks and the energy requirements of the data center.
1:35 Seems more like the total lack of testing to be the case. How hard would it have been for them to send a few of the precast segments to a materials testing lab? Where they could have used a hydraulic press to see how much load they could actually carry before breaking. As David Salisbury put it...
"Seems like a complete screw up to me".
@@DavidJohnson-tv2nn 1:35. Obviously there is failure, but not every slab is broken. 1 in 20 at this timestamp. Presumably an engineer would have designed those slabs. Design wise they may have been adequate.
My money is on an incorrect installation procedure. Guessing the slabs were being driven on after being placed, but before being bedded in grout, and fastened down. Slabs were all installed in Joe’s 31 July photos, but not fastened down (and presumably grouted either), until Brad’s 3 August video.
That and the poor quality contral during the casting, incorrect handling.
@@DessieDoolan My guess and it is only a guess is bad quality control and/or engineering failure. Why? Because some segments broke even before being installed.
As for only a few slabs being broken.... My guess is they would all fail under load at some point. Again, I'm not an expert on this so I could be wrong.
Is that cut up orange fiber optic cable in the junk pile? 2:04
@@bigtvjunky9119 2:04. Yes, 7 or 8 lengths of it. My eye was also drawn to the orange items to the left, only to realise those are fans.
Thanks Brad
Awesome well done.
Good views Brad. I looks like a lot of "Mega Pack" Transformers stock piled.
Yea, that makes me wonder if another bank of grid batteries are going to be install somewhere on Tesla property. More than plenty of room for that.
I believe that on average, TX generates much much more energy that it consumes. Would be interesting to see the figures but a BESS of any size would likely pay for itself in well under 5 years. Over here in the UK we are steadily increasing storage because of wind power generation excess.
@@memrjohnno About 7 miles north of the Gigafactory a 100MW battery farm was installed, plus two more at 50MW in the general area installed by Key Capture Energy Corp.
Merci👍👍👍
FYI: In Airwave Dynamics 8/9/24 video they're building three huge white tents @ the Hutto Railyard. I assume to protect cars from weather or dust/debris if they need to sit there for extended time before being loaded on the autoracks. Tesla supposedly also leased the building south of lot where the tents are being setup.
Could it be where they hide Cybercabs prior to delivery just before the 10/10 event? What’s the “REAL” purpose of the Multiple-Storey Parking Structure?
@@dewiz9596 That's the outbound railyard for Tesla. I assume all new designs are coming out of the engineering HQ in Palo Alto and would be transported to Texas in a car hauler like racing teams use.
The railyard is in Taylor Texas even though the sign on the water tower says Hutto.
@@BTSflyer I realize that, but people in the Tesla community have been calling it the 'Hutto railyard' since 2022. It's called 'Hutto railyard' on Google Earth. The whole railyard is the 'RCR Taylor Logistics Park'.
im not worried about the movie life anymore, i gotta et these gigafactories completed
👍
Tesla tiene que contener el gasto...o puede hacer fallida. (bajo beneficio sobre el producto y competencia mas barata y mejor acabado).
las medidas proteccionistas en EEUU pueden salvarlo, pero solo en su mercado.
Brad, what is the ground clearing across the river that you showed while closing out
No idea, it is not Tesla property that I know of unless he bought recently and no one discover the sale.
@@BTSflyer thank you.
@@BTSflyer From browsing the Travis County Appraisal District online property search, it look like EP Austin Purchase Company LLC owns all the parcels of vacant land on both sides of Highway 130 on the south side of the river. It’s a Deleware corporation, no idea who is behind it.
Taking their sweet time plumbing that outside cooler. Should have had it welded up in a week. Bet Elon is furious.
Ok, a little modern project management theory. Every project can be broken down into a number of tasks. Tasks usually have predecessors and dependencies, in other words tasks usually need other tasks done first and have other tasks that depend on them. So, as a project is planned you will figure out your critical paths or an ordered list of tasks that must before the project is finished. A complex project will be made up of many, many sub projects and paths, all of which when assembled together become the critical path to completion.
Now, we have all seen the funny sign about the triangle of effort, where they say, “ You can have it either fast, good, or cheap, not all three. Pick which two you want!” So as a project manager you not only look for the parts that must be done first and their order, but you also identify when they have to be done. So while it makes sense that the external cooling towers must be done before the project can be completed, it would make little sense to pay the company constructing it to rush its completion just to have it wait for another portion, say the scroll compressors which won’t be ready for two more months, or the electrical transformers that are six weeks out.
So, it all comes down to one the favorite jokes of the project manager. Two guys are out in the woods hunting for squirrels when they happen upon a bear. Not having a gun large enough for a bear, they are at some risk. One of the hunters, immediately reaches down and starts tightening his shoe laces. The other hunter looks at him and says, “What are you doing? You can’t out run that bear!” The other hunter looks at his friend and says, “I don’t have to outrun the bear, I just have to out run you!”
Many a time I’ve told that to a fellow subcontractor as I explained why I just had to make sure I was a little faster than he was, not necessarily as fast as we possibly could progress. No need wasting overtime, express shipping, or other expenses if you don’t have to. You just need to stay on path and make sure you aren’t the blocking issue.
So the contractor providing the cooling tower may be weeks ahead of his due date on the critical path or he may be woefully behind. If you aren’t looking at that project plan almost daily, it’s real hard to tell where they are at.
@@Bill_N_ATX Amen. What intrigues me most is the contractual setup that has been implemented by the Client in this contractor's heaven called GT.
LSTK? Cost-Plus? Call-off manpower and equipment? And who does the purchasing of the key materials? Suppose a contract requires a lot of structural steel, then the variations of the steel price alone may squash a general contractor out of existence. Also there is ample evidence that a lot of change orders must have been accommodated since the start of GT construction. If the Client knew this was going to happen from the outset, then it is unlikely that many LSTK projects were implemented. I would think that overall the Client has taken care of the major risks such as price variations for materials and protect timing. I don't know what is the term for such a flexible contractual arrangement, but from what we can see it seems everything moves swimmingly and a pause or delay or a rework order somewhere in the entire GT worksite doesn't seem to cause a ripple. I'm envious, having worked in LSTK projects with huge stresses on everybody being the norm.
What's that dirt work at the end of the video?
I imagine that module roadway was too noisy at speed. Probably going to asphalt the tunnel?
Meh
Love seeing all of the Cybertruck’s in the lot. I am looking forward freshly assembled Cybertruck’s drive through The Boring Company tunnel.
6:10 These transformers look like the units used on the Mega pack. Are they to replace the installed units or to build another Mega pack? Just here for storage to be placed in some other site later. Does anyone have any info.
My first speculation was that they were going to replace the existing Megapack transformers, since at the time there were 34, the exact same number of transformers used for the Megapacks. Now there are 52 of them! So that rules out the replacement theory. Haven't seen any new permits for Megapacks either. So it will be interesting to watch this to see what happens.
One thing Dessie suggested is possibly another Megapack installation as a backup power source for the data center. The downside to that is it would be very expensive and wouldn't buy them a whole lot of back time. Perhaps 30 minutes to a few hours depending on the number of Megapacks and energy requirements of the data center.
6:10. Same logo as those in the BESS. Magnetron of Columbia.
@@DavidJohnson-tv2nn Since it’s going to be a single-purpose compute cluster, they may decide to save a ton of money and just provide enough backup capacity to do an orderly shutdown in case of power loss.
@@Frank-gt7me I agree that they could get by with enough power to do an orderly shutdown. But... 52 transformers would mean 104 Megapacks. Much bigger than the existing Megapack installation. Probably one to Two hundred million dollars or more?
thanks for the flowers rachy, i seen u sneak over, i didnt know you still had a problem tlkn for yourself...
i gotta buy u something tomorrow for our anniversary, i almost forgot
big mama told me to tell them to pound salt and find another job
i have electricans that wire up mill sq ft factories, i think i know my electric, its the bunkers fckn with my electric
hey jr, its elon musk speaking to, do u wanna live in a bunker your whole life or would u rather move to cali and be able to play on the largest residential water slide ever, flick your lights on and off if u choose option B
tia your not gonna be down there around those harmful fumes all night, or around those burly men fantasizing about you, ita our 1 yr anniversary, u wanting ace to be crazy and act like his dad or what
